Where are the say macros defined?
by Wilmar Pérez 03 Mar '20

Hi all, Can anyone please point me at the configuration files where the definition for the say macros are? I mean. let's say I have this: session:execute('say', 'es number pronounced '..${some_number}); Then if ${some_number} is 403, then it gets pronounced as: "four .... hundred ... and ... three". Great! I have a problem witht the Spanish pronuntiation of 100 to 199 (yes, only that range) . It does not work as expected, So, I want to check where that is set and see if I can fix it. Thanks! Wilmar

Detecting FAS?
by Avi Marcus 02 Mar '20

02 Mar '20

I've yet again had users reporting issues and I found it there's FAS. I'd like to find or create something that notices and logs these issues immediately, before potentially weeks of customers experiencing degraded service. Before I re-invent the wheel, I'm asking if someone has a wheel around. I looked at these particular PCAPs and the ringing is quite clear to hear. Is there some scripts around that can flag calls, either based on simply the CDR or even with the PCAP as FAS? (e.g. FAS calls will rarely be over 2 minutes.) (Although, apparently there's many types of FAS. One more is to play a ring tone for 10-20 seconds and THEN try to connect the call. That way they get at least free 20 seconds of billable time and then proceed with business as usual.) https://blog.kolmisoft.com/fraud-false-answer-supervision-fas/ mentions key indicators in the CDR, but this isn't enough to definitely pin it as FAS. This could also occur upon reaching voicemail. - Short phone calls. - A caller which hangs up nearly 100% of the time. - High answer seizure ratio. - Lower ACD. They also mention this, which is what I'm interested in: "RTP audio signal processing: detection of voice, silence or ring-back tone." Is there some simple way to detect ring tones in the audio playback (which I might have to cut to ensure it's after the billing has actually started if the audio ring tone was passed in band) Thanks, -Avi Marcus BestFone
